CHARLES DU MQllTD, OF CEDAR FALLS,IOWA.

ACTUATING MEANS FOR WASHING-MACHINES.

To all whom it may concern Be it known that I, CHARLES M. DU MoND, acitizen of the United States of America, and a resident of Cedar Falls,Blackhawk county, Iowa, have invented certain new and usefulImprovements in Actuating Means for lv ashing-ll lachines, of which thefollowing is a specification.

My invention relates to improvements in actuating means forwashing-machines, and the object of my improvement is to furnish gearingand flexible connections for the ac tuating shafts thereof, which shallbe easy in operation as well as operable whether the cover of the tub beraised or lowered.

This object I have accomplished by the means which are hereinafterdescribed and claimed, and which are'illustrated in the accompanyingdrawings, in which:

Figure l is an elevation of my improved washing-machine, with partsbroken away to thereby better disclose the interior structures. Fig. 2is a top plan view of said machine. Fig. 3 is an elevation of saidmachine, taken at an angle of ninety degrees to the elevation shown inFig. l, and hav ing parts broken away. Fig. 4 is a detail elevation ofpart of the actuating-means for the plunger-head, taken on thesection-line a-b of said Fig. 2.

Similar numerals of reference denote corresponding .parts throughout theseveral views.

My improved washing-machine has its tub 1 mounted on legs, and has aswinging cover 2 for its open top, mounted on hinges 39. The cover 2 iscentrally vertically orificed to receive the tubular bearing 5 dependingfrom a base-plate 6 secured upon the top of said cover, and a verticalreciprocatory rock-shaft 3, having a plungerhead a on its lower endwithin said tub, is seated in said tubular bearing 5 to project abovethe base-plate 6. The base-plate 6 has integral spaced standards 7 and 8provided with alined bearings 19 and 20, respectively, for a rotaryhorizontal shaft 9, the latter having a crank 18 mounted on its endadjacent to the shaft 3, and said crank havlng a forked crank-pin 22mounted rotatably thereon.

The numeral 11 denotes a block mounted fixedly on the upper end of theshaft 3, and like arms 12 have their upper ends pivoted at 13 toopposite ends of said block, depending thence and having their otherends plv- Spccification of Letters Patent.

Application filed August 2, 1915. Serial No. 43,161.

oted to opposite ends of a link 21, the link havlng a middle projectionreceived between the forks of said crank-pin 22 and pivoted thereto on apintle 23. On the other or outer end of the horizontal shaft 9 isfixed-a gearwheel 24 in mesh with a larger gear-wheel 25, the latterrotatably mounted on a studshaft of the plate 6 on said cover 2.

An independent casting 27 is fixed on the tub 1 and has a stud-shaft 38on which is rotatably mounted the coaXially connected fly-wheel 28 andsmall pinion 26,.the latter being in mesh withthe gear-wheel 25, and theaxis of said fly-wheel and pinion pro-' longed being coincident andalined with the axis of the cover-hinges 39, whereby, when the cover isswung open, the gear-wheel 25 rldes upon said pinion without'unmeshingtherefrom, and permitting continued actuation of the said mechanismwithout need for starting it up again when the cover is lowered. Anydesired source of power may be operatively connected to said mechanismto drive same, but I have shown in the drawings means for manuallyactuating it. This means comprises a hand-lever 31 seated in a socket30, the latter mounted to rock on a stud-shaft 29 projecting from saidcasting 27. The socket 31 has an integral lug 32. A connecting-rod 34has one end bifurcated and pivoted on said lug, while its other end iscurved downwardly and pivoted on a crank-pin 35 on said gear-wheel 25.When said hand-lever is oscillated to and fro, its pitman 34 rotates thegear-wheel 25, which in turn, rotates the pinion 26 and the gearwheel 24at different rotational speeds. The shaft 9, by means of the flexibleconnectingmeans to the shaft 3, simultaneously rocks and reciprocatesthe latter to impart like movements to its plunger-head f within the tubl. The flexible connection for said shafts is simple, inexpensive,strong, and of easy operation.

Having described my invention, what I claim. as new, and desire tosecure by Letters Patent, is:

l. The combination with a support and a body hinged thereto, of areciprocatory rock-shaft mounted in said body, a rotatable shaft mountedon said body at an angle to the other shaft, and a movable joint-connection between said shafts, comprising a crank on thesecond-mentioned shaft, arms pivoted to the first-mentioned shaft, abifurcated crank-pin rotatably mounted on said crank, and a linkpivotally connected between and to the bifurcations of thecrankbodyhinged thereto, of a reciprocatory rock-shaft mounted in said body, arotatable shaft mounted on said body at an angle to the first-mentionedshaft, a gear-Wheel mounted on the second-mentioned shaft, another gearwheel in mesh therewith and also mounted on said body, a coaXiallyconnected fly-wheel and pinion mounted on said support with their axiscontinued in line with the hinge-connection of said body, and a movablejoint connection between shafts, comprising a crank on one end of thesecond-mentioned shaft, a bifurcated crankpin rotatably mounted on saidcrank, arms pivoted to opposite sides of the upper end of thefirst-mentioned shaft to depend swingingly therefrom, and a linkpivotally connected to and between the bifurcations of said crank-pinand also pivotally connected to and between the lower ends of said arms3. In combination, a reciprocatory rockshaft, a rotatable crank whoseaxis is losaid r cated at an angle to the axis of the rockshaft," andoperative connections between the crank and rock-shaft comprising anelement pivoted to the crank, an element pivotally connected to therock-shaft to swing only to and from the axis of the latter from and tothe crank, and a linking-connection pivotally connected to and betweensaid swinging element and said crank adapted to simultaneously rock andreciprocate said rock shaft.

4. In combination, a reciprccatory rockshaft, a rotatable crank, anelement pivoted to and depending from said shaft to swing in a planeintersecting the axis of the rock shaft, and linking connections betweenthe said element and said crank, operable to cause the element tosimultaneously swing to and fro and reciprocate while simultaneouslyrocking said shaft to and fro and reciprocating it.

Signed at Waterloo, Iowa, this 16th day of July, 1915.
